'wIoK FOR OIL sr'ovns.

Application filed September 9, 1926. Serial No. 134,378.

tinuous annulus or spiral, but a wick of this nature cannot of course bepacked 1nto small-space without folding Such folding destroys thestrength of a wick while shipping'in cylindrical form and requires toomuch space. ith' respect to a flat laminated wick, the user commonlyexperiences adifliculty either of having the wick buckle when formedinto an annulus or having an improper joint if out too short.

The principal objectot my invention is to provide a method for making alaminated wick which may be packed fiat for shipping and storage, andwhich will not buckle when curved to fit the adapter. A further objectis to provide a wick which shall be standardized so as'to fit a widerange of sizes of adapters.

Further objects and features of my invention will become apparent fromthe following description relating to the accompanying drawings whereinI disclose my preferred forms. The essential characteristics will besummarized in the claims.

In the drawings, Fig. 1 is a plan view of a wick embodying my inventionand laid fiat for shipping; Fig. 2 is a cross-section therethrough takenalong the line 2-42 on Fig. 1; Fig. 3 is a fragmentary plan view showingthe preferred means for fastening the laminations together; Fig. 4 showsthe manner of assembling the laminations; Fig. 5 shows the complete wickcurved to fit an adapter, and Fig. 6 shows a modified form of securingmeans for the. laminations.

In carrying out my invention, I propose to employ a plurality ofrectangular strips of non-combustible material such as commercialasbestos board, three of such strips being indicated in the drawing at10, 11 and 12 respectively. The retaining means for the laminations maycomprise ordinary wire staples as indicated at 15 and 16, the formerbeing placed transversely of the wick, and preferably near one end, andthe latter extending longitudinally of the wick and being spaced apart asuitable distance.

To make the wick I prefer to bend the laminations in the form of a halfcircle as shown in Fig. 4, and while maintaining them in this positionto bind them together with staples. This maybe'accomplished in asatisfactory manner by bending the laminations over a mandrel (notshown). Thereafter, the wick is flattened out and in doing so the wickmaterial adjacent the ends of the staples is stretched as shownon anenlarged scale in Fig. 8 thereby making relatively small openings 17 ateach end of the staple 16. The staples 15 do not make openings in any ofthe laminations, but hold at least one end of the wick tightly together.When the buyer purchases a wick in a flat package, he is enabled tocurve them to fit the adapter on his commercial oil stove, irrespectiveof the diameter of the adapter without danger of buckling the wick,sincethe. openings 17 allow slight relative movement between the staples andWick.

To secure standardization whereby only one size of wick may be furnishedfor a wide variation of sizes and types of adapters, I providelongitudinally extending graduations as indicated at 1, 2, 3 and 4 onFig. 1, and also transversely extending graduations as indicated at Aand B to fit adapters of different circumferences. graduations enableone to cut the wick to the desired depth, while the transverse 1graduations aid in determining the length. A chart showing the lines onwhich the wick should be cut to fit any commercial adapter -may befurnished with each wick.

Fig. 5 shows a wick cut and curved for insertion within an adapter. Thetop of the wick has been out along the line 3, and one end has been outalong the line A.

In Fig. 6 I have shown a modified form of clip fastener for securing thelaminations together. This comprises a sheet metal member 20, which maybe pointed as at 21 to perforate the sheets at one end, or both ifdesired. In practice I preferably perforate the sheets with only one endof such staple and lap the other end about the bottom of the bundle.

If desired the laminations may be secured together without bending themupon a mandrel. In such case however, in order to prevent buckling whenthe laminations are bent in the form of a circle, I prefer to make Thelongitudinal a slot in the laminations through which the metal fasteningmembers may extend. This will provide sufi'icient play between thelaminations to allow bendingofthe wick without buckling the innermostlamination.

Having thus described my invention, I

claim:

1. A method of making a wick for an" oil stove comprising superimposin aplurality of layer-sot fibrous material, bending 'the layers ina curvedform, binding: them together and: thereafter straightening themWl'lQl'GbY the wick may beshipped flat, and may be subsequently curvedfor use without buckling; i

2. A wick for oil stoves comprising superimposed layersof fibrousmaterial, spaced metallic fasteningdevices extending through thematerial and being clinched thereto, the perforations through which thedevices extend'being suflicientlyl large that one lamination may movewith relation tothe other to permit curving of the wick without bucklingto fit an adapter.

3. A. wick foroil stoves comprising a. plurality of superimposedlaminations having the same shape, staples extending through all of thelaminations and: clinched over at their free ends, the perforationsthrough which some of the staples extend being suflieiently large topermit relative movenally of the wick, and another line extending.

transversely of the wick, and said laminations being adapted to be outalong said lines to fit various sizes of adapters.

5. A wick for oil'stoves comprisinga plurality of superimposedrectangular shaped strips of fibrous material, wire staples extendingthrough the strips andi clinched thereto, the staples being so attachedto the strips that one strip may be moved slightly with relation toanother when thematerial is curved to fit an adapter andone of theoutside strips having graduations thereon extending in two directionsfor indicating the depth and length to which the lainina-- tions may becut to fit various sizes of adapters.

In testimony whereof, I hereunto aflixmy signature.
